简要总结
To evaluate and compare the plaque removal efficacy of a battery-powered toothbrush and a manual toothbrush following a single brushing.
详细描述
This is a single use, examiner blinded, randomized, two-period, cross-over, IRB-approved research study evaluating the single-use plaque removal efficacy of a new battery-operated toothbrush and a marketed manual toothbrush. This study will accept up to 64 subjects, 18-65 years of age, in anticipation that 60 subjects will complete the study. Qualified subjects with sufficient plaque, according to Rustogi Modified Navy Plaque Index (RMNPI) will be randomly assigned to one of two sequence treatment groups.
After the pre-brushing plaque evaluation at each of the evaluation visits, subjects will brush with the assigned toothbrush and toothpaste provided for timed brushing under supervision, in front of mirror.

- •Have agreed to comply with the conditions and schedule of the study.
排除标准
- •Have any physical limitations or restrictions which might preclude normal tooth brushing.
- •Have to be premedicated prior to dental treatment.
- •Have evidence of poor oral hygiene or rampant dental caries or calculus deposits that may interfere with plaque assessments.
- •Have evidence of major oral hard or soft tissue lesions or trauma at Baseline.
- •Have fixed or removable orthodontic appliances.
- •Have received a dental prophylaxis within a month prior to Visit
- •Have a history of a significant adverse event, allergy, or irritation that was due to oral hygiene products.
- •Have participated in another dental research study within 4 weeks prior to Visit
- •Therapy with any medications, currently or within the last 28 days, which might interfere with the outcome of the study by affecting tissue condition, or salivation, particularly chronic therapy or long-term use, as determined by the investigator.

结局指标
主要结局
Within-Treatment Whole-Mouth Differences (vs Baseline) - Plaque removal
时间窗: up to 2 weeks
Mean Change from baseline (pre-brushing to post-brushing) in plaque score after single supervised use based on all surfaces of the whole mouth measured. Scale used is Rustogi Modification of the Navy Plaque Index (RMNPI). Up to 504 sites scored in the mouth, with each score a 0 or 1, and subject scores an average over all sites measured. Minimum score of 0 and maximum score of 1. For each timepoint, a larger score means more plaque. For reduction from baseline, a larger score means a greater reduction in plaque.
